So, what is the best way to share sensitive information? What are the traditional and modern methods of sharing business files? What should be considered when choosing between secure file-sharing platforms? Dive into our guide and find the answers!

What is sensitive information?

Sensitive information is any form of data that requires high protection due to its confidentiality or personal nature. In business, it includes but is not limited to personal, financial, and business-critical data.

  • Personal information is any data identifying an individual, such as their name, address, phone number, social security number, birth date, credit card information, genetic and biometric data, sexual orientation, and other confidential information. Businesses typically collect and process personal information for specific purposes, such as employment or providing goods and services.
  • Financial information in business refers to data and reports that relate to a company’s economic performance. This information helps analyze a business’s financial well-being and make informed decisions about its operations and investments. Examples of financial information include balance sheets, income statements, cash flow statements, and financial ratios, which provide detailed information about a company’s assets, liabilities, revenue, expenses, and profitability.
  • Business-critical data refers to information vital for decision-making, planning, and managing operations. It can vary based on the industry and business needs. For instance, these documents may include customer data such as demographics, buying habits, and customer preferences. All this provides insights into customer behaviour and influences marketing strategies and product development.

Based on our experience, data security is only as strong as its weakest sharing point. So, you should take care of the file-sharing solution and data protection strategies you use.

Traditional methods of sharing sensitive information and their limitations

Although traditional data-sharing methods are becoming obsolete, they are still widely used. This is why it is crucial to carefully evaluate the security risks associated with each traditional solution to protect sensitive information.


Email is a popular file sharing solution as it allows for swift and easy transfer. This long-standing technology is user-friendly, especially for non-technical users, as no additional software is required.

One of the most significant limitations of email is the file size limit. Most email providers set a maximum file size to be attached to an email. If the file size exceeds this limit, you can’t send it, which can be a significant problem when sharing large files such as videos or presentations.

Another question – is it safe to send important documents via email? No. The lack of advanced encryption methods makes the transfer of confidential documents vulnerable to interception and unauthorized access. 

Moreover, emails can be lost or delayed in transit, and there is no way to ensure that the recipient has received the intended message or attachment.

Physical documents

Sharing files by courier involves sending them by mail. A courier service ships a USB or physical document and delivers it to the destination by air or ground. The limitations of courier services are that they can be slow and expensive, and there is no guarantee that your documents will be delivered safely. Furthermore, it may be challenging to track records if they are lost or stolen during delivery.

So, sending files by courier is like mailing a fragile package that may take a long time to arrive and could get damaged or lost along the way. 


Nowadays, the use of fax machines has declined due to the outdated method of sending and receiving paper faxes. However, some industries, such as banks, real estate, insurance, healthcare, and legal firms, still rely on it.

As for downsides, faxing can be costly as it requires a landline phone number, which is uncommon in most modern offices. In addition, high maintenance costs are involved, including ink, toner, and paper. Moreover, the recipient of your documents must also have access to a fax machine, which is often not the case.

Evidently, most business leaders prefer better alternatives for streamlined and secure file sharing. In this way, they avoid serious data breach consequences, including a loss of customer trust, legal penalties, and significant financial losses.

In fact, financial losses can amount to millions, as seen in the largest data breaches worldwide.

Modern ways of sharing sensitive information securely

Since traditional methods cannot always securely send sensitive information, those prioritizing security opt for online file-sharing solutions. Based on our observations, the most secure cloud services are as follows:

Secure virtual data room encryption

This secure file-sharing platform knows how to protect sensitive documents, satisfy security protocols, and build trust with your clients and partners.

In the tips below, we will elaborate on the data rooms features.

  • Safety through granular permission settings: A majority of virtual data rooms have granular permission settings. These define the user who has access to sensitive files. You can attach viewing permission to individuals but also to groups. You can even change authorization at any given time, which gives you full control over who sees what. Moreover, audit logs are a reliable source of information on activities in the secure data room.
  • Remote shred security: To increase document security, you can also establish the time in which a file will be available in the virtual data room. You can define for how long it can be accessed, and you can restrict access to those files even after someone downloads them. Combined with the granular permission you ensure double safety with your confidential data.
  • Certification compliance: Compliance with international standards is key to the data room software provider’s cybersecurity strategy. Thus, they prove the reliability of implemented data privacy and integrity controls. The most advanced certifications in the industry are ISO/IEC 27001:2013, SOC 1 or 2, GDPR, and HIPAA.
  • Visual protection: The most secure data room providers who know how to share sensitive information include innovative features for superior protection of sensitive information during complex business transactions. For example, the fence view prevents unauthorized viewing, screen capture, and printing. Secure spreadsheet viewer, in turn, makes working with data in Excel safe, enabling you to customize access levels. And watermarks make each document easily traceable, eliminating an unidentified data security breach.
  • Time and IP access restriction: With these advanced security features, admins restrict logins from specific IP addresses. In addition, they can set the session duration and the access expiration date. As a result, companies can control access to critical documents inside and deal with external parties.

If you compare virtual data rooms, you will notice the last two options are not available from all data room vendors but only from market leaders who know how to share sensitive information securely.

With granular permissions and remote shred, virtual data rooms simplify take your security control to the next level, designating who can access sensitive data at any given moment.

Factors to consider when choosing a method to share sensitive information

Our findings indicate that the key factors to consider when choosing among secure file sharing services are security, accessibility, confidentiality, traceability, and compatibility.


Security is the most critical factor to consider when sharing sensitive information — the method of sharing must be secure enough to protect the information from unauthorized access. End-to-end encryption, a dedicated user account, password protected, data leak prevention mechanisms, and two-factor authentication are some measures you should look for.


The method of sharing should allow the recipient to access the information quickly. If the recipient has to jump through hoops or have specific technical knowledge to access the information, they are unlikely to want to spend time on it.


The recipient should be the only person who can gain access to the information. Using a method that allows multiple recipients increases the risk of data falling into the wrong hands.


If the information falls into the wrong hands, it should be possible to trace who accessed it and when. It will help identify the leak’s source and take appropriate action.


The method of sharing should be compatible with the recipient’s system. Data exchange may fail if the recipient cannot access the information due to compatibility issues.

Considering these best practices for handling sensitive information, you can ensure that the information is shared with the right people. Check out top VDR providers and choose what best fits your needs!
